We will also use qualitative data to accomplish the following goals: 1) to explore subjects' experiences with the study's activities; 2) to understand barriers to participation; and 3) to explore patient and family experiences with the intervention. To obtain these goals, we will contact a total of 30-40 participants, selected from all subject groups, to participate in one-on-one semi-structured interviews during which they will be asked to share their experiences as a study participant and their perspectives on study activities.
